Unable to set target temperature (room_setpoint) #3

Closed mihsu81 closed 2 years ago

mihsu81 commented 2 years ago

Hi @wichers, Using an Opentherm gateway from DIYLess (seems to be a newer version of Ihor Melnyk's original gateway) I'm unable to set the room_setpoint from HA 2021.8.6. https://diyless.com/product/esp8266-opentherm-gateway

In the below example the room_setpoint was set to 19 through a physical thermostat. When trying to set it to 22 through HA, the climate component sends the correct info, but the opentherm_gw.climate component sends 19 again.

Could you please help me troubleshoot this issue?

Thanks in advance.

Hi,

I have exactly that same problem - after changing target temperature through Home Assistant, it's going back to temperature set by physical thermostat.

Is there any solution to get it working?

Hi @piio, I didn't manage to get around the issue. Same issue with an OpenTherm Gateway from http://otgw.tclcode.com/. I think it is related to the Thermostat, because when i load a thermostat firmware on the Opentherm Gateway from DIYLess, it controls the boiler just fine. I have an OpenTherm DOTROOMTHEAA thermostat from Daikin and a D2CND024A1A boiler also from Daikin. I got busy with other projects and neglected the gateway.

Looks like it had nothing to do with the build. My thermostat doesn't support remote setpoint. Daikin DOTROOMTHEAA is using undocumented OpenTherm messages to control the gas boiler. I'm trying to document them and maybe @wichers can implement them?
